Notes and guide lines.
Sprongs are designed
to be "pushed past", not driven
over and not
to be pushed into ground.
fence under ground cable should be buried
below potential wheel-rut depth or the
installation of a 'bridge' option stop
We recommend the
use of 6 foot post in most cirmstances
and 7 foot in soft or sandy conditions.
For cattle only one
pair of sprongs need to be installed
For calves install
one pair of sprongs at 900mm and one
300-400mm above ground.
For sheep install
two pair of sprongs at 700mm & 900mm
and "bungis" *
at 300mm & 500mm above ground.
Care must be taken with bungi cord
to prevent injury. Consult manufacture.
Bungi cord has a
limited life and tends to wear where
the wheel runs over it. We recommend using Beattie electric bungi for its long lasting characteristics. Bungi also
stretches and is unsuitable for heights
where the sprongs used.
A wire "halo"
system can be used to tie posts together
at ground height where soft soil tends
to make posts move.
